Motion detector

The displacement sensor is also called a linear sensor, a sensor that converts displacement into electricity. Displacement sensor is a linear device belonging to metal sensing. The function of the sensor is to convert various measured physical quantities into electricity. It is divided into inductive displacement sensor, capacitive displacement sensor, photoelectric displacement sensor, ultrasonic displacement sensor, and Hall Displacement sensor.

In this conversion process, many physical quantities (such as pressure, flow, acceleration, etc.) often need to be transformed into displacement first, and then into electricity. Therefore, the displacement sensor is an important basic sensor. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. Mechanical displacement includes linear displacement and angular displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical type (such as self-generation type) and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor develops rapidly, and its application is increasingly widespread.
